The FKAA assumed owner and operator responsibilities of the Duck Key Wastewater Treatment Plant in 2006. Extensive upgrades were completed in 2012 increasing capacity and improving treatment to the stringent Advanced Wastewater Treatment (AWT) standards, ensuring discharges do not exceed 3 milligrams per liter of nitrogen and 1 milligram per liter of Phosphorous.
The facility now treats approximately 138,000 gallons of wastewater per day, removing approximately 97% of nutrients (total nitrogen, total phosphorous, total suspended solids and biological oxygen demand) prior to discharge in the injection well. To further minimize this discharge the effluent receives tertiary treatment, producing high quality reclaimed water that is distributed to residents and businesses for use in non-potable applications such as irrigation, car-washing and boat washing. This last step further reduces nutrient discharges and saves valuable potable water resources that would have been otherwise expended for these non-potable uses.
